Extended Data Fig. 6: Bivariate relationship between plot relative aboveground net biomass change (ΔAGB) and basal-area-weighted mean vegetation traits (A–E) and climatic variables (F–I) across Amazonian forest plots.
From: Basin-wide variation in tree hydraulic safety margins predicts the carbon balance of Amazon forests
Due to high standing aboveground biomass variability across sites, we computed relative ΔAGB values as: ((AGB end – AGB start)/census length)/AGB (time-weighted mean standing woody biomass). Each point indicates a forest plot. Information about each plot and the observation period used can be found in Supplementary Table 5. Stem wood density data were extracted from the Global Wood Density database65,66. KEN plots were excluded from all forest dynamics analyses because of a fire event that occurred in the region in 200466 and may still be affecting biomass accrual. Regression lines show significant relationships using standard major axis (SMA) models after Bonferroni correction for multiples hypothesis testing. Supplementary Table 3 shows the results of the SMA models.
